Abstract

The invention provides a GPSR security routing protocol implementation method based on a block chain trust model. The method comprises the following steps of: S10, enabling a trusted authority (TA) to initialize vehicle network system parameters according to an RSA algorithm; S20, when the vehicle enters the Internet of Vehicles, performing network access identity authentication; S30, periodically broadcasting a real coordinate position after any node vehicle-mounted unit OBUi completes network access authentication, adjusting a trust value of the OBUi based on a Tmbore trust model, and completing node routing role judgment and block chain storage according to the trust value; and S40, performing secure routing calculation. According to the GPSR secure routing protocol implementation method based on the block chain trust model, the mobile edge computing technology and the block chain technology are combined, and the Tmbore trust model is designed and used for improving the security of a GPSR routing protocol, realizing secure and reliable storage of trust values and lightweight discrimination of authenticity and reliability of routing nodes, and improving the security of the GPSR routing protocol, and improving the security of the GPSR routing protocol is improved.

Description

technical field [0001] The invention relates to the field of vehicle networking application technology, in particular to a method for implementing a GPSR security routing protocol based on a blockchain trust model. Background technique [0002] As a core technology of the intelligent transportation system, the Internet of Vehicles (IOV) plays a huge role in real-time dissemination of road traffic emergency information, assisted safe driving, and information sharing between vehicles. Vehicles follow the DSRC protocol to broadcast information such as position, speed, direction, and road conditions, making the information transmitted between users very easy to be intercepted and forged by malicious attackers. It is easy to suffer from Sybil attack (Sybil), slot attack (Sinkhole) and other routing message forgery and spoofing, and these attacks will seriously endanger driving safety. [0003] There are three main types of IoV routing protocols: Topology based routing protocol (...
